San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.
San Diego Rat Control Tip of The Week
Is Trapping Rats Legal?
When it comes to trapping rats, there has been a misconception for quite some time as many house owners think it is illegal. This is nothing but a myth, so if you are planning to get a trap to remove the rats in your home, you are legally allowed to do so.
Rats are one of the most destructive household pests. Being carriers of diseases and different types of disease-causing organisms, they contaminate the surface of your home and any of your food substances that they come in contact with. Also, these pests bring in highly inflammable materials into your home and rip off electrical cables that are capable of igniting a fire. All these clearly show how dangerous they are to you and your property and why you need to get rid of them as early as you can.
Apart from the need to get rid of this major household pest, the use of traps is the fastest and the best way to get rid of rats. Although, the use of glue traps has been labeled by PETA and The Humane Society as an inhumane way of trapping rats. With the exception of the inhumane aspect of glue traps, the use of traps is completely legal.
So if you are thinking of removing the rats in your home, you can go ahead and use a trap.
